Atomic layer 3D printing

28.01.2020

The prospects of additive manufacturing (3D printing) as a versatile tool for prompt and inexpensive prototyping are extremely promising. This family of methods are set to make fabrication processes faster, more efficient in terms of the raw materials and energy required, and more flexible. However, additive manufacturing has not yet been broadly applied to micro and nanotechnology. Lithography, as the methods used for structuring in microelectronics are called collectively, is based on the repetition of complex multistep procedures in each of which a so-called “resist” that serves as a template is applied and later removed.

Not only is current lithography slow, it also wastes materials and energy, is poorly adapted to combining a large number of distinct materials, and extremely costly in terms of capital expenses.


A team of scientists and engineers led by Prof. Julien Bachmann from FAU plan to combine the expertise of the various consortium partners in the chemical control of ultrathin coatings (“atomic layer deposition”), in gas delivery, microelectromechanical devices, and microprocessing and automation, in order to demonstrate the potential of “atomic-layer 3D printing”, that is, the generation of arbitrary shapes with a vertical resolution in the order of one atom (or a tenth of one nanometer).

The consortium includes the companies ATLANT 3D Nanosystems, Femtika, and SEMPA Systems as well as the Institute of Electrical Engineering of the Slovak Academy of Sciences and FAU, and will be funded by approximately 3 million euros over a period of two years in the framework of the European Union’s “Fast Track to Innovation” programme.

The goal of the project is to design, build and test an industrial prototype of the atomic-layer 3D printer that can then be sold commercially.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
